Wish I had found this forum earlier
Newbie to Passats and have only just purchased a 05 highline (1.9tdi) for the wife today but it looks like I may have some water ingress probs (passenger doors not opening off the key and reversey noisey thingy not working either) Fools rush in and all that, hopefully everything else will be ok 
Glad my T4 doesnt have all this electrical jiggery pokery ;)
